X-6=10 X=?

Answer:

20 minutes( 0.3333 hours) after they leave the station will they be 50 km apart, if the Two trains on opposite tracks leave the same station at the same time. One train travels at an average speed of 80 km/hr and the other travels at an average speed of 70 km/hr.

Step-by-step explanation:

The given is,

                  One train travels at an average speed of 80 km/hr

                  The other travels at an average speed of 70 km/hr

Step:1

     Formula to calculate the distance traveled by two trains,

     Distance traveled by two trains = (Rate of speed of train one +

                                                          Rate of speed of other train) × Time

        From the given the above equation becomes,

        Let, h = Time taken to each the distance

                                         50 = ( 80 + 70 ) h

                                           50 = (150) h

                                                 = 0.3333 hours

                                                 = ( 0.333 × 60 )          ( ∵ 1 hr = 60 minutes )

                                               h = 20 minutes

Step:2

           Check for solution,

           From equation (1),

                          50 = ( 80+70 ) (0.3333)

                          50 = (150)(0.3333)

                          50 = 50

Result:

         20 minutes( 0.3333 hours) after they leave the station will they be 50 km apart.

Answer:

V=14

Step-by-step explanation:

Well its a supplementary angle if you add everything together.

We know theres a 90 degrees angle and a 34 degree angle.

90+34=124

124+4v=180

Since if you add everything up its a straight line

Solve the equation normally

56=4v

14=v

Step-by-step explanation:

it's very easy you just need to use c squared equals a squared plus b squared

Answer:

a. Opens downwards (since the the value of 0.4 is negative)

b. Has a maximum (since the parabola opens down)

c. Is not a reflection of the parent function (since the parabola is widened by the scale factor of 0.4).

d. Is a stretch since it is widened by the scale factor of 0.4

Answer:

i think you do 5 ÷30

#juice wrlds not dead

Answer:

1/6 represents the 10 out of 6, but it is known as 1 in this answer because it is a choice out of the other 6.

1/6 = ?/30

1/6 · 5/5 = 5/30

5/30 large stuffed animals will be given away. I presume this is the correct answer.

Answer:

343 ft^2  (Closest to Answer D)

Step-by-step explanation:

The triangle on the left has height 24 ft and base 18 ft, and therefore, by the area-of-a-triangle formula A = (1/2)(b)(h), the area of the triangle is

A = (1/2)(24 ft)(18 ft) = 216 ft^2.

The semicircle on the right has radius (18 ft)/2, or 9 ft.  Using the area-of-a-semicircle formula A =(pi)(r)^2/2, we find this particular semicircle to have area

A = (pi)(9)^2/2, or approximately 127 ft^2

Adding these two subareas together results in total area

A = (216 ft^2) + (127 ft^2) = 343 ft^2   (Answer D)

Answer:

28m⁷n⁵

Step-by-step explanation:

You would first multiply 14 by 2. You would then multiply (which is really addition when it comes to exponents) your like-term exponents.

(14m²n⁵)(2m⁵) =28m⁷n⁵

14(2) = 28

m² + m⁵=m⁷

n⁵ + 0 = n⁵

Answer:

[tex]28 {m}^{7} {n}^{5} [/tex]

Step-by-step explanation:

14*2=28; m^2*m^5=m^7.

When you're working with multiplication of powers, you have to add the exponents. For example

[tex] {x}^{4} \times {x}^{2} = {x}^{6} [/tex]

Because

[tex] {x}^{4} = x \times x \times x \times x \\ {x}^{2} = x \times x \\ {x}^{4} \times {x}^{2} = x \times x \times x \times x \times x \times x = {x}^{6} [/tex]

The correct answer would be J; [tex]\frac{1}{2} r + 2[/tex];  

Step-by-step explanation:

Using the algebra;

[tex]\frac{1}{2} * r[/tex] = [tex]\frac{1}{2} r[/tex]

[tex]\frac{1}{2} * 4 = 2[/tex]

Altogether this would give "J" as the answer.
